Speed is too high and influences the problem of gas mud-water separation effect is with mud is run, and effectively increases separating capacity.
The mechanism for the shallow layer precipitating theory that the present embodiment is related to is very shallow equivalent to one between every two pieces of inclined paralled plates to sink
Shallow lake pond, it is mainly clearance height the advantages of shallow layer precipitating theory, the residence time is short and floor space is small, specifically includes at 3 points：One
It is that make use of lamina flow principle, improves the disposal ability of sedimentation basin, second, particle settling height is shortened, so as to shorten precipitation
Time, three are the increase in the desilting area of sedimentation basin, so as to improve treatment effeciency；Based on the theoretical sedimentation basin of shallow layer precipitating
It is 36m to cross flow rate3/(m2.h), the disposal ability than general sedimentation basin is higher by 7-10 times, is a kind of new and effective settling apparatus.
The principle for the shallow layer precipitating theory that the present embodiment is related to is to set a length of L in tube settler pond, and level stream speed is in pond
V, particle settling velocity are u0, in the ideal situation, L/H=v/u0, when L and v values are constant, pond depth H is more shallow, the suspension that can be removed
Particle is smaller；If with horizontal baffle, H is divided into 3 layers, is H/3 per depth layer by layer, in u0With v it is constant under conditions of, only need L/3, just
Can be by u0Particle remove, namely total measurement (volume) may decrease to original 1/3；If pond length is constant, because pond depth is H/3, then
Horizontal flow velocity rises to 3v, and it is u to remain to settling velocity0Particle remove, namely disposal ability improve 3 times；Simultaneously by sedimentation basin
It is divided into n-layer can and disposal ability is improved n times.

The upper flow section of liquid is closed, the upper cross-sectional area of air water mud mixed liquor is more than the air water mud of three phase separator structure in the prior art
The upper gross sectional area with sludge sinking bidirectional flow of mixed liquor；Air water mud Disengagement zone is also referred to as shallow layer precipitating area；Clear water zone is not
It is the settling zone of three phase separator of the prior art；Mud return line belongs to preventative set parts.
3. gas-liquid-solid three-phase separator according to claim 1, it is characterised in that in use, folded plate type swash plate, sludge return
Flow tube and biogas pipe, which combine, forms three phase separator, and the air water mud mixed liquor in reaction zone enters air water mud mixed flow gap, air water mud
When mixed liquor is by air water mud mixed flow gap, streamline is oblique by being vertically changed into, because basal area reduces, in air water mud mixed liquor
Bubble collides swash plate under higher flow velocity and quickly rises to gas collection area along swash plate, and air water mud mixed liquor is by upper folded plate
Influence, formed shrink, extruding and diffusion, be advantageous to the effusion with the gas in gas sludge；It is theoretical based on shallow layer precipitating,
In the shallow-layer swash plate that swash plate is formed, laminar flow condition is beneficial to the three phase separation of air water mud, after gas rising is collected into gas collection area
Pond body is discharged by biogas pipe, the sludge quantity taken out of by clear water gap is considerably less to be disregarded so that can be ignored, and is non-removal object,
Therefore, scum silica frost amount is few, and the processing water for reaching clear water zone belongs to the water quality for meeting stream requirement, and processing water is discharged via outlet canal
Pond body, handling the flow velocity of water will not have an impact to the processing procedure and result of air water mud mixed liquor；Enter mud collection area along swash plate
Sludge under the protection of upper folded plate, do not influenceed by the ascending current by air water mud mixed flow gap, sludge passes through sludge reflux
Pipe returns to reaction zone, realizes the quickly and efficiently separation of air water mud three-phase.
